Spray whichis thrown up by the gases through aperture 10 will strike against the under side of the cap 11 and will drop ofi' harmlessly from the point 13, back into the cell.

In case any spray opening 9, it will be prevented from spurting by the apron 12, but will fall harmlessly upon the top of the cell, whence it may be collected by any convenient means.

One embodiment of the present invention has been described in detail. Many modifications will occur to those skilled in the art. It is intended in this case to cover all such modifications that fall within the scope of the invention as defined by the appended claims.

Having thus described my invention, what as new and desire to secure by Letters Patent of the United States, is:
